Warning
Undesired movement of the connected actuators and non−
defined switching states of the electronics can cause injury
to human beings or damage to property.
Before carrying out installation and maintenance work,
switch off the following:
the operating and load voltages on the higher−order
system (e. g. CP field bus node)
separate power supplies.
Warning
Incorrect or missing earthing can cause interference due to
electromagnetic influences.
Connect the earth connection on the side of the housing
(see Fig. 1/1) with low impedance (short cable with large
cross−sectional area) to the earth potential.
You can then guarantee electromagentic compatibility in ac
cordance with the EMC guidelines.
Caution
Only connection X1 is used for the power supply to the
sensors. Do not connect any external supply to terminals
+ and of X2 and X3. Otherwise the input module may be
damaged.
